+# Hashtag & Mention Extractor for ServiceNow
+
+A simple yet useful **ServiceNow Background Script** that extracts all hashtags (`#example`) and mentions (`@user`) from any text input using regular expressions.
+
+This script demonstrates how to apply JavaScript RegEx in server-side ServiceNow logic to parse, analyze, or extend user-generated text - ideal for text-analysis demos or lightweight automation projects.
+
+---
+
+## 💡 Example Use Cases
+- Automatically identify hashtags and mentions in **incident comments**, **knowledge articles**, or **survey feedback**.  
+- Build internal analytics to track trending topics like `#VPN`, `#email`, or `#network`.  
+
+---
+## 🚀 How to Run
+1. In your ServiceNow instance, navigate to **System Definition → Scripts – Background**.  
+2. Paste the script from this repository.  
+3. Click **Run Script**.  
+
+---
+
+## 📦 Reusability
+The logic is **self-contained** within a single function block — no dependencies or external calls.  
+You can easily **copy and adjust it** to fit different contexts:
+- Use it inside a **Business Rule**, **Script Include**, or **Flow Action Script**.  
+- Replace the sample `demoData` with a field value (e.g., `current.comments`) to analyze live data.  
+- Adjust the regex to detect other patterns (emails, keywords, etc.).  
+
+This makes it a **plug-and-play snippet** for any ServiceNow application or table that requires quick text pattern recognition.
+
+---
+
+## 🔧 Possible Extensions
+- Parse live table data (`sys_journal_field`, `kb_knowledge`) instead of static text.  
+- Store extracted tags in a custom table for analytics.  
+- Schedule a nightly “Top Tags” report with **Flow Designer** or **PA Widgets**.
